`The present invention relates to baking pans' of the multiple type in which a plurality of metal receptacles are mounted together by means of a metal framework so that the plurality of receptacles may be placed within and removed from the oven and handled as a single unit.

The invention is embodied in a multiple pan of thetype described, wherein a plurality of receptacles are connected together by means of `end plates to which the individual receptacles are secured, and cross bars connecting the end bars between the receptacles, the cross bars being also directly connected to the receptacles. Protector plates are providedat the opposite ends of a series of receptacles, as is common in the art. In this multiple pan structure the present invention provides means on the end plates whereby the pans may be stacked one upon another in stable position with the receptacles nested, but out of contact with each other, so that the inerior surfaces will not be marred by the exteriors of the superimposed receptacles.` i

The multiple pan structure embodying the invention provides also `a novel cross bar construction and end bar construction by which stronger and more satisfactory connections are obtained in assembling the several receptacles with the end bars and cross bars.

The features and advantages of the invention will appear more fully from the following description, reference being had to the accompanying drawings wherein a preferred form of the invention is shown.

In the drawings,` Fig. 1 is a fragmentary plan view of a multiple pan at an intermediate stage in its manufacture, showing one receptacle completely attached to the supporting end bars and cross bars, with the adjacent receptacle omitted to illustrate the initial construction of the end bars and cross bars.

Fig. 9 is a sectional view taken on the same line as Fig. 3, showing a slightly modified form of the d cross bar construction. i

Referring now to the drawings, the invention is embodied in a multiple pan which comprises a plurality of metal receptacles lil that are secured in a framework composed of end bars il and l2 and cross bars I3 and `ifi- The receptacles lll are the usual rectangular shape, having side panels I5 and I6 and end panels ll and I8. The receptacles l@ have folded sections I9 and 2li at the ends, the sections being folded over the end panels of the receptacle in the usual mannernC-i- Protector plates 2l are provided across the outer side faces of the end pans at the opposite ends of a rseries of receptacles in the usual manner, having their end portions bent at an angle about the corners of the end pans. Theend bars Il and I2 are extended beneath the protector plates 2 l, as shown at 22 in Fig. 2, and are welded thereto. Each end bar i l and l2 also has an inwardly pressed offset portion 23 vfor each receptacle Il), which offset portion is adapted to fit in between the folded over sections I9 and 2i) of the receptacle, l

, Each end bar l I and l2 is constructed as shown best in Figs. 5, 6 and 8 by folding a strip of metal 265 upon itself to form a double thickness thereof. One edge 25 of the strip 2d projects beyond the other edge liti and is curled toward the other edge 26 slightly in the formation of the end bar. Also, vmidway between the offset portions 23, eachend bar has a tongue 2l punched out of the inner f.

wall 2B and turned down in the plane of the outer wall 29 of the end bar, theV edge portions of the tongue Z'l being bent over on the body of the tongue as shown at Sii in Figs. 2 and 6 to provide a smooth contour around the periphery of the tongue 2l. The function of the tongue 2l is to provide a guiding and stabilizing element which, when one multiple pan unit is stacked upon another, will t between the `rims of adjacent receptacles upon the subjacent pan unit, thus locating the stacked units and preventing the outside surfaces of the receptacles in the superposed unit from engaging and marring the inner surfaces of the receptacles. The inner wall 28 of the end bar is split directly over thev center line of the tongue 2l down a short, distance below the top level of the edge 255, and lugsl and 32 are turned inwardly as shown best in Fig. 8. The outer wall 29 is cut out as' shown at 33, to provide a recess in the upper edge 26 thereof which is .somewhat wider than the distance between the lugs 3| and 32. The function of the lugs 3l and 32 is to cooperate with certain portions of the cross bars such as I3 and I4 in interconnecting the cross bars with the end bars.

As shown best in Figs. 1, 3 and 7, the cross bars are made up of two rectangular frames 34 and 35, placed end to end between adjacent receptacles and connecting one end bar Il! to the opposite end bar I2. The adjacent ends of the frames34 and 35 are tied together by a cross piece 36upon the frame 35 and a crossI piece 3'I on the frame 34. The cross piece 31, shown lbest in Fig. 3, has a portion 38 bent over to form a hook which ts over the cross piece 36. Each of the frames 34 and 35 in the unassembled form as shown in Fig. 7 has its side portions 39 and 40 curved inwardly at the top edge to facilitate the curling of the receptacle and this top edge together in the assembly operation carried out later. The side portions 39 and 4D have seats 4I and 42 formed by pressing a portion of the side piece inwardly, and these seats are adapted to receive the free ends of the lugs 3| and 32 in the manner shown in Figs. 5 and 6. 'Ihe side pieces 39 and 40 are cut diagonally across the seats 4I and 42 and extended beyond the seats where they are bent toward each other to provide flanges 43 and 44 which abut the end bars and are secured thereto by welding. It will be noted from an examination of Figs. 5 and 6 that the ilanges 43 and 44 lie below the level of the lugs 3I and 32 andjfit atly against the inner Wall 28 of the end bar. Before the receptacles are assembled with the end bars and cross bars, these elements of the cross bars are connected together by securing the ilang'es 43 and 44 to the end bars. A receptacle is then. placed within each rectangular area bounded by the cross bars I3 and I4 and the end bars II and I2. The receptacles then have their upper edges 45 curled outwardly and downwardly over the upper edges of the side portions 39 and 40 and the upper edges 25 of the-end bars. The upper edges of the lugs 3| and 32 being also disposed within and forming a part of the periph ery of the receptacle receiving framework are curled over with the top edge of the receptacle. The showing in Fig. 4 illustrates the manner in which the top edge of the end bar is curled over the top edge 26. It will also be noted that the top edge 45 of the receptacle lil is curled around and turned up inside the edge 25.

Referring now to Fig, 9, in this form of the invention the cross bars are composed of two rectangular frames 34 and 35 which are identical with the rectangular frame shown in Fig. '7. A rectangular frame 46 is interposed between the frames 34 and 35 and is connected thereto by cross pieces 41 and 48 on the frame 46 and hooked portions 49 and 5I] on the frames 34' and 35'. While the frames 34 and 35 and the frames 34' and 35 have been described as rectangular v frames, it is evident that theydo not form a closed rectangle because the anges 43 and 44 are separated at their inner ends by a narrow space. Therefore, the term rectangular flange as used hereiny should not be considered as limited to a closed rectangle.

While the preferred embodiment of the invention has been shownl and described, it is tobe understood that it is capable of many modications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed inthe appended claims in which it is my intention to claim all novelty inherent in the invention as broadly as possible in view of the prior art.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is: v
